Remember the difference between update and upgrade. An OS upgrade, since back like when 98 went to XP, usually requires a format and clean load. And the less aware that don't have a storage drive lose the last photo of their dog and them with their late mother in the process.

Has Micro$oft yet told us what the value add is that make Windows 10 mo' betta?

Not broke = don't fix.

I have Windows 7 SP1 on 5 computers and have no issues at all. Homegroup is working fine and I stream from one to the other or to the Chromecast on my TV just fine. 1 old soldier continues to march on XP, as I just don't want to take the time to move stuff and format the C: drive just to upgrade to Windows "anything but XP" just to say I am running "anything but XP". I don't care that Micro$oft has disowned XP. I don't need them to patch or update anything on a computer that is off the network 99% of the time. The only time I enable the wireless NIC is when I need to move a file in house or mail one out.

Standard disclaimer - But that's just me.
